L'o a/L w/wm t may concer/1,:

Be it known that I, IRVING L. HoTALrNG, a citizen of the United States, reslding at Riverton, in the county of Burlington 'and State of New Jersey, have invented certain new and useful Improvements in Curtainpivoted at 13 in the end of the curtain-stick Fixtures, of which the following is a specitii 10, the inwardly-extending arm of said head cat-ion.

This invention relates to curtain-fixtures having attached thereto the outer end ot the leaf-spring 1 1, While the u pwardly-extendin'g 6 5 of that type wherein a curtain-stick secured I arm is provided on its outer face with a fricin or to the lower portion oi" a curtain is provided with a head at each en d carrying devices engaging a guiding-groove of the Window-frame and automatically resisting, through frictional engagement with the guide, the upward pull ot t e curtain-roller spring. while permitting the curtain and fixture to be freely drawn downwardly.

The object of the present invention is to provide a simple, economical, and efficient curtain-fixture; and to this end the invention comprises a device chiefly characterized by the provision oi a curtain-stick and a head having a fixed pivotal connection. to the stick and an elast ic bearing on the guide.

My invention will be readily understood l when considered in connection with theiaccompanying drawings, showing preferred l embodunents thereof, whereinl Figure 1 is a longitudinal sectional view of l one end of a curtain-stick equipped with one t form of my improved lholding device. Fig. l 2 is a similar view of the opposite end ot a curtain-stick equipped with a sinilar device provided with a roller instead of a frictiontip. Fig. 3 is a similar view showing a modied form of head and tip. Fig. 4 is a similar view illustrating a still further modified form device, the two parts of which have a knuckle engagement with each other g and Fig. 6 illustrates a still turt-her modification whereinthe head is equipped with a pair of frictionally-retarded or brake rollers.

Referring to the drawings, 1() designates in all'of the views an end portion of a tubular l of up. Fig. 5 illustrates a double form of uw I curtain-stick, such as is commonly carried in v a pocket formed in and across the lower end of a spring-actuated curtain or shade, and 11 designates in all of the several views a bentleaf-spring, the inner free end ot which bears against the bottom of the curtain-stick in a I manner to force outwardly or toward the casingguide the upright member of an l L-shaped fixture-head that is pivot-ally l mounted in the end of t-he curtain-stick, as

j tion-pad 14, that is normally pressed bythe spring 11 int-o engagement with the casingguide, the pad-contacting surface of which is indicated at 15. In order to provide for a 7o limited angular play of the elbow-lever, the

10 is slotted, as indicated at 16, to receive the uprightarm of the lever, said slotextending inwardly a slig t distance beyond 7"' the inner edge of thearm.

Fig. 2 shows a construction generally similar to that of Fig. 1, the upright arm of the elbow-lever 12EL carrying a roller 17, this construction being suitable for/curtains or 8o Shades equipped with relatively light curtainwinding springs, wherein theout-Ward thrust of the iixture-head against the guide caused by t-he s ring 11 affords a sufficient resistance to t e upward pull of the curtain-roller 8 5 spring to maintain the curtain. stationary in any adjusted position.

In the form of the invention illustrated in Fig. 3 the upright arm of the elbow-lever 12b is cored out, as indicated at 18, in which core 9o is placed a compression-spring 19, the upper end whereof bears frictionally against the periphery of a roller 20, mounted on a pin 21, carried by the upper end of the arm. Preterably and as herein shown the roller has an 95 enlarged or lost-motion bearing on its pivotpin, which permits a frictional engagement of the periphery of the roller not only with the upper end of the spring, but also with the lower end of a vertical slot in the upper roo end of the arm in which the roller is mounted, thus increasing the braking eiiect on the roller produced by the upward pull of the. curtain induced by the curtain-relier spring.

Fig. 4 illustrates a form of the device Io5 wherein the upright arm of the elbow-lever 12C has non-rotatably mounted therein a bearing member 22, that is loosely surrounded by a ring 23, preferably of rubber or leather, producing a frictional engagement with the 11o periphery of the bearing member 22, thus aiiording a suflicient brake to the i'rec rotation of the ring. 23 to resist the norinal upward pull of the curtain.

Fig. 5 illustrates a modification of the invention involving a double foi-in of the ,lixtiire-head previously described adapted to ail'ord a contact of the head with the guidegroove both above and below the end of the curtain-stick. .ln this view the elbow-lever 12d is provided just below its pivot with a depending tooth 24, that engages a notch 25 in theeupper end oi: a depending companion lever 26, that is pivoted to the end ot the curtain-stick at 27 and works in a. slot 16 in the lower portion oi" the curtain-stick. rlhe outer free ends ot' the levers nia);v be equipped with plain rollers 17u or a-iijy' other forni oi guide-contacting tip. It will be observed. that in this forni of the invention the action of the spring 11 is to throw the upright arin oi the elbow-lever 12d outwardly or toward the guide and that the tooth 24, enga-ging the notch 25 of t-lie lower lever 26, at the saine tinie iinparts to the latter a similar outward movement towaid the guide, thus maintaining both tips 17a in engageineiit with the latter.

For the purpose of securing a longer and niore extended bearing ot' the fixture-head on its guide the construction illustrated in Fig. 6 ina-jy' be advantageously ein ployed, wherein the elbow-lever 12e is cored, as at 18, and provided with a compression-spring 19, the opposite ends of which bear rictionalljf upon the adjacent portions of the peripheries ot a pair ot guide-rollers 2S and 29, mounted on pins 30 and 3l, respectively, in the upright arn'i of the lever, said spring exerting a braking eiiect upon both rollers and causing both to drag upon the surface of the guide. contact-ed thereby. This construction and that of Fig. 5 are pzn'ticulai'lj,vv uset'ul in connection with very wide curtains requiring a long curtain-stick, since it tends to prevent cantin ot' the latter when manipulated.

The operative principle oi' all the several forms of the invention shown is the saine. The elastic or resilient inner or horizontal arni oi' the elbow-lever represented bjr the spring 11 always acts to torce t-he upright arm ci' the lever and the fixture-tip carried thereby iiito engagement with the casingguide with inore or less friction, according to the forni of tip emplojjed, which will depend `upon the degree ot resistance necessari in the iixtiire to ovei'conie the iiornial pull ol' the curtain-roller spring and hold the curtain exteiiding arni being adapted to bear at its end on a. guide ot the casing, substantiallj.7 as described. l

2. A curtain-fixture comprising a hollow curtain-stick, and an elbow-lever having inwardlpT and outwardlj,lextending arms relatively' to the stick pivoted in the end of said stick, the inwardly-extending arm of' said lever being elastic and bearing upon the stick, and the outwardly-extending arm being adapted t-o contact aguide of' the window- -casing, substantialljT as described.v

3. A curtain-fixture comprising a hollow curtain-stick, and an elbow-lever having inwardly and outwardly extending arms relativelyT to the stick pivoted in the end of said stick, the inwardly-extending arin of said lever terminating in a spring bearing upon the stick, and the outwardly-cxtending arm terminating in a friction-tip adapted to engage a guide of the casing, substantially as described.

4. A cui'tain-ii'xturc comprising a curtainstick, an elbow-lever pivoted to the'end of the stick and having an inwardly-extending elastic arn'i bearing upon the stick, and an auxiliaryy lever pivoted to the saine end ofthe stick and connected with said elbow-lever by a toothed connection, the outer ends ot said levers being adapted to contact a guide ot the casing, substantially as described.

5. A curtain-tixture comprising a hollow curtain-stick, an elbow-lever pivoted in the end ot the stick and having an inwardly-extending spring-arm bearing upon the stick,

and an armiliarir lever pivoted in the same end ot the stick and connected with said elbow-lever bj; a toothed connection, the outer ends of said levers being adapted to contact a guide of the casing, substantially as described.
